This API is deprecated. Please use the [E-Waybill APIs from the unified set available here](/cleartax-docs/e-invoicing-api/introduction-to-e-invoicing-api.md).
{% endhint %}

#### Response Structure:

ClearTax Error response will always tell you 2 things:

1. What is the error?
2. Where is the error?

You can get this error responce with different HTTP status code based on the API you are consuming. Example: You can get it with `400` Bad Request or with `200` OK

The `errors`object under `errorResponse`will always have the list of errors found in your payload. The `message` will explain what the error is and it's always paired with the `error_id`Error response

![](/files/-MDU-oTMNCRVMpIUw-qp)

The `error_sources` object will direct you to the specific field in which the error was found.
